Specification of Letters Patent.

Application filed September 8, 1910. Serial No. 580,981.

PATENT, mun.

To all whom it may concern:

Be it known that I, CHARnEs H. KOFSKE, a citizen of the United States, residing at Waterloo, in the county of Blackhawk and State of Iowa, have invented certain new and useful Improvements in Brake-Beams; and I do declare the following to be-a full,

clear, and exact description of the invention,

such as will enable'others skilled in the art to which it appertains to-make and use the same.

This invention relates 'toimprovements in brake-beams for railway'rolling stock. 3

The object of the invention is to provide an improved brake beam which will -be simple, strong anddurable in construction, ef-

ficient and reliable in operation, light in weight and well adapted to the purpose for which it is designed. i

With this and otherbbjects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claim.

In the accompanyingdrawings: Fi ure 1' ra eam;

is a plan view of my improved ke Fig. 2 I15 a rear view of the same; Fig. 3 is a vertical sectional view on the line 33 of Fig. 1;v Fig. 4 is asimilar view on the line 4.4 of Fig. 1; Fig. 5 is a detail view of the beam with the parts separated. i

' My improved brake beam comprises a lower metal plate or bar 1 which may be of any suitable size and has its 0 posite ends bent upwardly to form end anges 2 as shown. Arranged above the bottom piece 1 and between the end flaniges 2 is a top piece 3 said piece being also n the form of a fiat metal plate. Between the bottom and top-pieces 1 and 3 of the beam is arranged 'anintermediate piece l which'is in the form of a metal plate constructed as shown whereby the same serves as a truss brace to prevent the bending or buckling of the brake beam when great strain is ap lied thereto. The ends of the bracing mem er 1 are enlarged as shown at 5 andclosely engage 'or' abut against the end fla'nges 2 of the beam whereby said bracing member is rigidly held when strain isapplied to the beam; As hereinbefore described the bracing member 4 is formed in the shape of a truss brace or is formed at an angle on opposite sides of its center toward its ends. At the center of the member is formed a forwardly projecting tongue .6 which lies between'the center of the upper, and lower plates of the beam Patented Dec. 2?, 1910. i

when the parts are assembled. The upper and lower plates and, the truss brace are secured together midway between their ends by two bolts orrivetsasshown.

' Around the center of the upper and lower 7 and an eye bolt 10 as shown. The pins 10,

are provided'to prevent the beam from swmgin out of osition. The brake heads Shave ormed t erein anra erture 11 and a notch 12 which'are provided to receive different styles of hangers (not shown).

The brake heads 8 are refera'bly provided on their outer curve surfaces with laterally projecting lugs 11 through'which are-formed alined apertures. The lugs 11 areadapted to engage in. recesses 12' formed in\the inner surfaces of the shoes 9. ,;On the inn r surface of the shoe 9 betweemthe recesse 12 is formed a lug 13 rovided with an aperture'which, when the slEoe is engaged with the head, is adapted to aline with the aperturesl, in the lugs on the head. When the shoe is thus engaged-with the head a fastening pin or key 14 is inserted through l alined. apertures in the lugs 11 and 13 thereby securely holding the shoe in place. Thepin 14 is applied to the. apertured' lugs 11 and 13 through a groove or channel formed in the outer curved surface of the brakehead.

A-brake beam constructed in accordance 'with my inventionwill possess great strength and willbe capable o resisting any .st-rain placed u on the same in the application of the bra e. The beam is supported by'suitable supporting chains in the usual or any desiredmanner.

From the foregoing description taken in connection with the accompanying drawings .the construction and operation of the inventionwill be readily' understood without requiring a more extended explanationrfio Various changes in the form, prop ion and the minor details of con struction may be resorted towith-out departing from the principle or sacrificing any of the adVELIk tages of the inyenti o-n as defined in cheappended-.cla-im.

Having thus what I claim is 1 p A brake beam comprising a lower late having its opposite ends bent upward y to form end flanges, an upper plate-arranged above said lower plate and between said flanges, abracing member arranged between said plates and having its ends engaging the described my invention,

' end flanges of the bottom plate and a lever attaching clip arrangedaround the beam to hold said parts together in operative position.

In testlmony whereof have hereunto set my hand in presence of two subscribing witnesses. v n CHARLESHENRY KOFSKE.
